EXTERIR TIREeARMOR.

Specification of Letters Patent.

Patented Mar. 29, i921.

Application filed October 11, 1920. Serial No. 415,981.

To (LU whom t may concern.'

ie it known that l, `W1LL1AM F. MGMONE- can. a citizen et the United States, residing at Hazleton, in the county or" Luzerne and State oi Pennsylvania., have invented new and usei'ul improvements in Exterior Tirermor, ot which the following is a specification.

The object of my present invention is the provision of' a simple, easily applied, eiiicient and durable exterior armor for tires, and one calculated to increase the tractive capac ity ot a wheel and prevent skidding thereof in addition to practically precluding the possibility oit puncture.

To the attainment ot' the Jforegoing the invention consists in the improvement as hereinafter described and definitely claimed,

ln the accompanying drawings, hereby made a part hereofz- Figure l is a side elevation showing` a portion of a wheel equipped with my improved exterior armor.

Fig. 2 is a view, partly in edge elevation and partly in radial section, of the equipped wheel.

Fig. 2aN is a detail longitudinal section showing the manner of joining the sections or shoes of the armor.

Fig. 3 shows a modified strap designed to be employed in lieu of straps 10.

Fig. i is a detail transverse section illustrative of another modiiication.

Similar numerals of reference designate corresponding` parts in Figs. l, 2 and 2a.

rlhe wheel illustrated may be and preterably is ot the ordinary well known construction, the same being provided with a conventional or any other approved pneumatic tire l;

My novel exterior armor is 'formed in a plurality of sections or shoes, and each section includes a body 2 of pressed steel. The said body 2 is curved in the direction ot its length and transversely conformably to the tire and is provided at its sides and adjacent to its ends with lateral apertured lugs 3. four in number. At one end the b'ody 2 is provided with a radially disposed flange 4, and the opposite end of the body is slightly oiset as indicated by 5 to receive the adi acent end of an adjoining body 2, and is also provided with a radial ange 6, Fig. 2a. In addition to the body 2 each armor section comprises calk members 7 on each of which is a transverse series of c-alks or teeth 8 separated by intervening spaces 9. This provision manifestly confers on the armor the ,capacity to prevent skiddingof the vheel equipped with the armor. rThe calk members 7 may be permanently adapted to the body 2 or may be detachably connected to the body, the latter provision being resorted to when deemed expedient so that the calk members may be removed for summer use of the armor or to give place to new calk members when occasion demands. Then the sections are assembled in proper working relation on a wheel the pla-in end ot one section. body is socketed in the offset end oit the body of an adjoining section as clearly appears in Fig. 2a. It will also be noted that when the sections are assembled as shown in Figs. l and 2a, the iang'es G by abutting against each other will preclude endwise movement or the sections with respect to each other.

To secure the armor sections on a wheel I provide straps 10 and 1l complementary to each section, the straps 11 being comparatively long ain/d equipped with buckles 12 and the straps 10 being provided at intervals in their lengths with apertures 13. l would also have it here understood that with a view to increasing the durability of the straps it is within the purview of my invention to provide metallic wear plates 14 in the loops of the straps 10 and ll, and to reinforce the apertures 13 in the straps ll through the medium oi metallic eyelets as illustrated.

In applying the armor sections to the wheel I prefer to pass the straps 11 at the inner side ot. the fellyand to the outer side ot the wheel, and at the latter point to conncct the straps l0 to the buckles l2.

It will be apparent from the foregoing that my novel armor is susceptible oi quick and easy application without the assistance ot skilled labor or tools. and that when properly applied the armor is adapted in addition to preventingT puncture to increase the tractive capacity of the wheel and to effectively prevent any tendency oi the same to skid.

In Fig. 3 I show a strap 10L recessed atl0b to straddle a. spoke of a wheel and having tabs 10. designed to cooperate with buckles 12. Said strap l0a is designed to be used in lieu of the pair oit straps 10, Figs. l and 2,

:ind is advantageous inasmuch as it is calculated to prevent undue creeping of the anti-skid device about a, tire.

It is Within the purview of my invention to ineke each armor section or shoe as shown in Figs. l and 2 or as shown in Fig. 4. The armor section 2X shown in the latter figure is peculiar and advantageous in that it is provided with tivo longitudinal air chambers 3X, designed to allow a, 'free circulation of air in order that no undue heat may injure the rubber tire or casing. The said chambers 3X are afforded by merely bulging the body of the section or shoe 2X and therefore do not add appreciably to the cost of providing the section or shoe.

Having described my invention, what I claim and desire to secure by Letters-Pabent, is

An exterior tire armor section or shoe comprising a metallic body curved length- Wise and transversely conformebly to a, tire und having one of its end portions plain and its other end portion equipped With an offset and also having radial flanges for traction purposes, one of the said Hanges being spaced beck from the end of the plain portion, and the other iange being disposed at the end of the offset.

In testimony whereof I aix my signature. 30
